Background: Coronary heart disease (CHD) remains the leading cause of death in the United States, yet the benefits of modern cardiovascular care are not equitably distributed. Social determinants of health (SDoH), which includes economic stability, education, healthcare access, and neighborhood environment, may substantially shape outcomes among patients with CHD. Our study evaluates the joint association of SDoH burden and CHD with mortality outcomes. Methods: We analyzed adults ≥20 years from the National Health and Nutrition Examination Survey (NHANES) 2000–2018, linked with the National Death Index through 2018. Cumulative SDoH burden was derived from eight domains (employment, poverty-to-income ratio, food insecurity, education, healthcare access, insurance, housing, marital status), categorized as low (0–2), moderate (3–5), or high (6–8). Weighted Cox proportional hazards models estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause and cardiovascular mortality by SDoH burden, stratified by CHD status, with sequential adjustment for demographic and cardiometabolic factors. Results: Among 49.3 million U.S. adults (mean age 46.1 ± 15.6 years; 44.8% female), 3.7% had CHD. Those with CHD were older (64.7 vs 45.4 years, p < 0.001), more often non-Hispanic White (94.2% vs 81.5%), and had greater waist circumference (106.1 vs 87.5 cm) but lower cholesterol (176 vs 202 mg/dL, p < 0.001). Participants with high SDoH burden had lower income and education. In weighted regression, higher SDoH burden and CHD were independently associated with greater all-cause and cardiovascular mortality. Fully adjusted models showed high SDoH burden tripled all-cause mortality risk (HR 3.00, p < 0.001), while CHD further amplified risk. Compared with low SDoH/no CHD, those with CHD and high SDoH burden had nearly a 14-fold higher all-cause mortality (HR 13.6, p < 0.001) and 17-fold higher cardiovascular mortality (HR 17.7, p < 0.001). Findings were consistent across sex, race, and metabolic subgroups, with mortality hazards often exceeding tenfold among those with both CHD and high SDoH burden. Conclusions: Cumulative SDoH burden is strongly and independently associated with mortality among adults with CHD, with evidence of a synergistic effect between biological and social vulnerability. These findings underscore the need for policies and interventions addressing upstream social inequities to improve survival in cardiovascular populations.

Abstract Background Valvular heart disease (VHD) and atrial fibrillation (AF) frequently coexist, presenting complex clinical challenges despite advances in diagnostics and therapeutics. Together, they contribute substantially to cardiovascular mortality. However, epidemiological patterns vary across demographics and regions Methods Mortality data from 1999–2023 were obtained from the CDC WONDER database. Deaths attributed to VHD (ICD-10: I30-I52) with co-diagnosed AF (ICD-10: I48) among adults ≥ 45 were included. Age-adjusted mortality rates (AAMRs) per 1,000,000 population were calculated. Autoregressive integrated moving average (ARIMA) models were used to project mortality trends through 2035. Results From 1999 to 2023, there were 172,511 VHD and Afib-related deaths in adults ≥ 45. AAMRs increased until 2021, followed by a slight decline to 8.86. The overall AAPC for VHD with AF was 4.01%. AAMR increase was consistent across all age groups, highest seen in 65 + individuals. Males had consistently higher AAMRs than females. AAPC for males was 4.44% and for females 3.52%. Non- Hispanic White had the highest AAMR (10.56 in 2021), followed by Hispanics (4.19). Regionally, the West had the highest AAMR (11.27), followed by Mid-West (9.94). Non-metropolitan areas had higher AAMR 8.96 compared to metropolitan areas (AAMR: 7.59). Most VHD related deaths were reported in inpatient settings (n = 396,451) and 12% involved co-diagnosed AF. Conclusion Mortality associated with VHD and AF in the U.S population aged ≥ 45 has shown a concerning increase. Predictive models indicate this trend may persist, highlighting the need for early detection, equitable healthcare access and public health interventions tailored to high-risk populations.

Background: With a global prevalence of 586,000 cases of thyroid cancer, thyroid cancer is the 10th most common malignancy. Despite advancements in early detection and treatment, the incidence of thyroid cancer continues to increase in the United States. This study aims to assess disparities in mortality trends stratified by age, sex, race, geography, urbanization status, and location of death, to guide clinical decision making. Methodology: Mortality data on thyroid cancer were extracted from the CDC-WONDER database, from 1999 to 2020. Age-adjusted mortality rates (AAMRs) and crude mortality rates (CMRs) per 100,000 were stratified by age, sex, race, geography, urbanization status, and place of death. Joinpoint regression software was used to determine annual percent change (APC) and average APC. Results: From 1999 to 2020, a total of 46,777 deaths attributed to thyroid cancer occurred in the United States, among individuals aged ≥ 25 years. The overall AAMRs showed a positive trend, increasing from 0.6 per 100,000 (95% CI: 0.5-0.6) in 1999, to 0.7 (95% CI: 0.7 - 0.7) in 2020. 56.63% of those deaths, or 26,493 deaths, occurred in women. When stratified by age group, the 85+ age group had the highest CMR of 9 (95% CI: 8.3-9.7). The racial group with the highest AAMRs were Whites, with an AAMR of 0.7 per 100,000. Mortalities in the South region accounted for 33.5% of total deaths. Moreover, metro areas also had higher mortality rates than non-metro areas. Information regarding place of death was only available for 8242 deaths, with 2763 of them occurring in medical settings. Conclusion: Mortality rates in all population groups increased from 1999 to 2020, with variations in mortality rates noted among them. Risk stratification of high-risk groups, such as older people and women, and targeted interventions are key for addressing disparities in mortality rates. Presentation: Saturday, July 12, 2025

Yet, when we examine the United States, one of the most developed nations globally, a concerning picture emerges in the realm of public health significant racial and ethnic disparities in disease outcomes. Among these, endocrine- related mortality, which includes conditions like diabetes, thyroid disorders, and hormonal imbalances, stands as a silent yet significant contributor to health inequities. Using data from the CDC WONDER database, this study seeks to explore these trends in depth, not just to identify the gaps but to shed light on the lived experiences of marginalized communities who bear the brunt of these inequities to pave the way for more equitable healthcare interventions. Methods: This descriptive study analyzes Racial and Ethnic Disparities in Endocrine-Related Mortality in the United States from 1999-2022, utilizing data from CDC Wonder database. We searched the Center for Disease Control database from 1999 to 2022 for mortality statistics with an underlying cause of death. The age-adjusted mortality rate (AAMR) was calculated per 1,000,000 deaths. We evaluated the AAMR using demographic variables such as race/ethnicity, geographic density, gender, age (25 or above), place of death, and the US Census Region. Temporal trends were assessed using Joinpoint regression software. Mortality rates by age, demographics, and place of death were examined. Statistical analysis calculated endocrine-related mortality rates and trends, with findings deemed significant at P &lt; 0. 05. Results: Between the years 1999 to 2022, 837203 deaths were recorded to be caused by endocrine-related disorders. An overall rising mortality trend from 1999-2022 among all races and ethnicities is noted, except in Asian or Pacific Islander, Black or African American, and Hispanic patients, which shows a rise till 2020 followed by fall in age-adjusted mortality rates (AAMR) in 2022. A significant dip in mortality rate was seen in 2017 in all racial and ethnic groups. American Indian or Alaska Natives showed highest AAMR (181.87, 95% CI 178.06-185.69) followed by Black or African Americans (149.78, 95% CI 148.9-150.64), Hispanic or Latinos (112.33, 95% CI 111.59-113.07), Whites (94.31, 95% CI 66.6-68.25), Asian or Pacific Islanders (67.45, 95% CI 66.6-68.25). American Indians or Alaska Natives exhibit the steepest rise over time (APC -0.32 TO 8.85) from 1999-2022. Conclusions: Mortality due to endocrine-related disorders has dramatically increased over time. Significant disparities have been noted among different races and ethnic groups, with the highest rate among Americans and the lowest among Asians. This underscores the need for targeted interventions for specific racial groups to reduce the mortality burden of endocrine-related diseases. Presentation: Sunday, July 13, 2025

Background: Diabetes mellitus (DM) is a global health burden, contributing significantly to mortality and comorbidities, including chronic kidney disease (CKD), which remains a leading cause of morbidity and mortality, especially in type 1 and type 2 diabetes. Methods: This retrospective cohort study examined mortality data from the United States from the CDC WONDER database, which gathers data from death certificates. Particularly, deaths from renal problems (ICD-10 codes E10.2-E14.2) linked to diabetes were the emphasis. Sex, age, race/ethnicity, and geographic location were among the important demographic factors that were used to stratify the data for the analysis. Temporal trends were examined using linear regression, while geographic disparities were assessed through chi-square tests and regression analysis. A significance level of p&lt;0.05 was used for all tests. Results: According to the data, the death rate from diabetes increased significantly between 1999 and 2020. Between 1999 and 2020, the number of deaths from diabetes rose from 2,325 to 74,296. From 13.12 per 100,000 in 1999 to 276.92 per 100,000 in 2020, the age-adjusted death rate increased significantly, indicating a fivefold rise in mortality rates over the 21 years. After 2010, the pace of increase became especially steep, with notable yearly increases, especially in the years after 2013. In the Hispanic population alone, the number of deaths from diabetes more than quadrupled between 2013 and 2020, rising from 5,378 in 2013 to 10,395 in 2020. Male mortality rates were consistently greater than female death rates, indicating gender-based inequities as well. By 2020, there were 41,225 male deaths from diabetes (AAMR: 351.07). Notably, the death rate for men was almost 60% greater than that for women in 2020, with rates rising more sharply for men, particularly from 2010 onward. Significant differences in diabetes-related mortality were also observed by geography. Florida, Texas, and California had the largest mortality burdens; in California alone, 73,185 deaths, or 13.8% of all deaths, occurred. Lastly, more deaths were found to occur in medical facilities, especially inpatient settings, as well as at home or in hospice care, indicating a change in the place of death. Conclusions: The study shows a significant rise in diabetes-related mortality in the US over the past two decades, with males experiencing a higher mortality rate. Geographic disparities are also evident, with Southern states and large states like California, Texas, and Florida contributing disproportionately. The shift in death places suggests increased reliance on medical facilities, home care, and hospice care. The study calls for targeted public health interventions to address the growing burden of diabetes-related mortality, particularly in high-risk regions. Presentation: Sunday, July 13, 2025

e16456 Background: Gastric cancer is one of the significant contributors of mortality and morbidity, especially in older patients. Analyzing national trends in the Disability adjust life years (DALY) helps identify the evolving burden of this disease among patients older than 70 years and highlights the regions requiring particular interventions. Methods: Using Global burden of disease data from 2021, national DALY rates per 100,000 people aged 70 and over with gastric cancer were assessed. The Estimated Annual Percentage Change (EAPCs) with p value taken as a statistical measure of significance, was used to evaluate trends from 1990 to 2021. Results: The analysis displays considerable contrasts in the trends of gastric cancer burden across nations. From 1990 to 2021, a rising trend in DALY EAPC was seen in Egypt (1.01883; 95% CI: -0.1931- 1.958) followed by Honduras (0.3262; 95% CI: 0.0177- 0.7456) and Lesotho (0.2253; 95% CI:-0.1326- 0.6995). Conversely, Austria (-0.7368; 95% CI: -0.7646 to -0.7087), Republic of Korea (-0.7095; 95% CI: -0.7620 to -0.6442) and Singapore (-0.6923; 95% CI: -0.7286 to -0.6553) reported a prominent decline in DALY EAPCs, reflecting significant progress in reducing burden. The DALY rates in 2021 also varied dramatically among nations. Highest DALY rate was observed in Bolivia (4882.7; 95% CI:3782.9- 6349.7) underscoring highest impact on healthcare system. Conversely, Morocco (329.69; 95% CI: 234.64- 410.12) recorded lowest DALY rate indicating comparatively better disease control or lower incidence. Conclusions: While some nations demonstrate remarkable progress in mitigating the burden of gastric cancer, others still face significant challenges. Highest increase in EAPC in Egypt, Honduras and Lesotho whereas significant decline in Austria, Korea, and Singapore indicates areas of target public health efforts. Future research should focus on understanding the causes of these disparities and evaluating the impact of interventions across it. DALY and EPAC.
